不锈弹簧钢丝生产工序复杂,周期长,影响钢丝性能的因素很多。多年来的生产经验和试验研究认为,提高不锈弹簧丝性能的三大工艺环节是:①钢的化学成分和盘条表面;②钢丝的热处理工艺;③钢丝的冷拔工艺。通过几年来的生产和试验研究,基本掌握了高强度不锈弹簧钢丝性能变化规律。我厂在生产抗拉强度为150-200公斤/毫米~2的1Cr18Ni9Ti弹簧钢丝时,采用如下生产工艺:①钢的合碳量为0.08-0.11％,Ti/C应大于5.5;②钢锭表面经砂轮修磨,锻坯扒皮和精选盘条表面以及采用高表面质量钢丝生产方法;③钢丝直径≤φ9.0mm的半成品和成品前,在连续炉固溶处理;④钢丝冷
Stainless steel spring wire production process is complex, long cycle, many factors affect the performance of steel wire. Over the years the production experience and experimental studies that improve the performance of stainless steel wire three major aspects of the process are: ① the chemical composition of steel and wire rod surface; ② wire heat treatment process; ③ wire cold drawing process. After several years of production and test research, the basic grasp of high-strength stainless steel spring wire changes in the law. I plant in the production of tensile strength of 150-200 kg / mm ~ 2 1Cr18Ni9Ti spring steel wire, the use of the following production process: ① steel carbon content of 0.08-0.11%, Ti / C should be greater than 5.5; ② ingot surface by Grinding wheels, forging billets and the selection of the surface of the rod and the use of high surface quality steel production methods; ③ wire diameter ≤ φ9.0mm semi-finished products and finished products before the continuous solution treatment; ④ cold wire
